# Components:
→ Bread Base
01 - 1 large loaf brioche or challah bread, cut into 1-inch cubes (approximately 18 ounces)
02 - 2 medium ripe bananas, mashed
03 - 6 large eggs
04 - 1.5 cups whole milk
05 - 0.5 cup heavy cream
06 - 0.5 cup light brown sugar
07 - 0.25 cup granulated sugar
08 - 2 teaspoons vanilla extract
09 - 2 teaspoons ground cinnamon
10 - 0.25 teaspoon ground nutmeg
11 - 0.25 teaspoon fine sea salt
→ Cream Cheese Swirl
12 - 8 ounces cream cheese, softened
13 - 3 tablespoons granulated sugar
14 - 1 large egg yolk
15 - 1 teaspoon vanilla extract
→ Cinnamon Sugar Topping
16 - 2 tablespoons unsalted butter, melted
17 - 0.33 cup light brown sugar
18 - 1 tablespoon ground cinnamon
# Method:
01 - Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Arrange half of the cubed bread evenly in the prepared baking dish.
03 - In a large bowl, whisk together mashed bananas, eggs, milk, cream, brown sugar, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until smooth and well combined.
04 - Pour half of the custard mixture over the bread cubes, pressing gently to ensure the bread absorbs the liquid.
05 - In a medium bowl, beat softened cream cheese, sugar, egg yolk, and vanilla extract until smooth and creamy. Dollop spoonfuls of the mixture evenly over the soaked bread.
06 - Top with remaining bread cubes, then pour the remaining custard mixture over the casserole. Gently press to ensure all bread is fully moistened.
07 - Mix melted butter, brown sugar, and cinnamon together. Drizzle or dot the mixture evenly over the casserole surface.
08 - Cover the casserole tightly with plastic wrap or aluminum foil and refrigerate for a minimum of 6 hours, ideally 8 hours or overnight.
09 - Preheat oven to 350 degrees Fahrenheit. Remove the casserole from the refrigerator while the oven reaches temperature.
10 - Place the uncovered casserole in the preheated oven and bake for 40 to 45 minutes, until puffed and golden brown. A knife inserted in the center should come out clean.
11 - Allow the casserole to cool for 10 to 15 minutes before serving. Serve warm, optionally topped with maple syrup or a dusting of powdered sugar.
